Addgene Comments
Using FLEX vectors in vivo: LoxP sites in FLEX plasmids are known to recombine during DNA amplification and viral vector production, which may result in a minority of Cre-activated (i.e., "flipped") viral vectors. Addgene has measured this occurs in 0.01-0.03% of viral vectors in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo. To address this, we recommend titrating to find the optimal AAV dosage required for Cre-dependent transgene expression and function in vivo. This may include reducing the viral vector dosage in order to reduce the likelihood of Cre-independent expression.

杀菌效果是由微生物所接受的照射剂量决定的,同时,也受到紫外线的输出能量,与灯的类型,光强和使用时间有关,随着灯的老化,它将丧失30%-50%的强度。紫外照射剂量是指达到一定的细菌灭活率时,需要特定波长紫外线的量:照射剂量(J/m2)=照射时间(s)×UVC强度(W/m2)照射剂量越大,消毒效率越高,由于设备尺寸要求,一般照射时间只有几秒,因此,灯管的UVC输出强度就成了衡量紫外光onclick="g(消毒设备);">消毒设备性能最主要的参数。在城市污水消毒中,一般平均照射剂量在300 J/m2以上。低于此值,有可能出现光复活现象,即病菌不能被彻底杀,当从渠道中流出接受可见光照射后,重新复活,降低了杀菌效果。杀菌效率要求越高,所需的照射剂量越大。影响微生物接受到足够紫外光照射剂量的主要因素是透光率(254 nm处),当UVC输出强度和照射时间一定时,透光率的变化将造成微生物实际接受剂量的变化。
优点
大多数紫外线装置利用传统的低压紫外灯技术,也有一些大型水厂采用低压高强度紫外灯系统和中压高强度紫外灯系统,由于产生高强度的紫外线可能使灯管数量减少90%以上,从而缩小了占地面积,节约了安装和维修费用,并且使紫外线消毒法对水质较差的出水也适用。
研究使用现状
目前国内研究、生产和应用污水紫外线消毒器还很少。天津大学的顾平等人以天津纪庄子污水处理厂的深度处理出水为研究对象,进行了静态和动态试验,确定了紫外线剂量与细菌存活率之间的关系,并设计出能产生紊流的紫外线消毒器,多元水环保技术产业(中国)有限公司研制生产的封闭式消毒器可处理100~500m3/h水量,并且在onclick="g(游泳池);">游泳池的循环水消毒中已有应用,模块化敞开式消毒器可根据用户需求具体设计安装。烟台市套子湾污水厂的深度处理采用了敞开式紫外线消毒工艺,可向城市提供4×104m3/d的工业回用水,目前运行状况良好。
紫外线消毒适用范围:
2.3.1 适用范围:
用于室内空气、物体表面和水及其它液体的消毒。
2.3.2 紫外线消毒灯和紫外线消毒器
2.3.2.1 消毒使用的紫外线是C波紫外线,其波长范围是200-275nrn,杀菌作用最强的波段是250-270nrn,消毒用的紫外线光源必须能够产生辐照值达到国家标准的杀菌紫外线灯。
2.3.2.2 制备紫外线消毒灯,应采用等级品的石英玻璃管,以期得到满意的紫外线辐照强度。
2.3.2.3 紫外线消毒灯可以配用对紫外线反射系数高的材料(如抛光铝板)制成的反射罩。
2.3.2.4 要求用于消毒的紫外线灯在电压为220V、环境相对湿度为60%、温度为20℃时,辐射的253.7nm紫外线强度不得低于7ouW/cm2(普通30W直管紫外线灯在距灯管1米处测定,特殊紫外线灯在使用距离处测定,使用的紫外线测强仪必须经过标定。)
2.3.2.5 紫外线灯使用过程中其辐照强度逐渐降低,故应经常测定消毒紫外线的强度,一旦降到要求的强度以下时;应及时更换。
2.3.2.6 紫外线消毒灯的使用寿命,即由新灯的强度降低到70Uw/cm2的时间(功率≥30w)的灯,或降低到原来新灯强度的70%(功率<30w=的时间,应不低于1000h。
2.3.2.7 目前我国使用的紫外线消毒灯有下述几种
(1) 普通直管热阴极低压汞紫外线消毒灯:灯管采用石英玻璃或其它对紫外线透过率高的玻璃制成,功率为40W、30W、20W、15w等。要求出厂新灯辐射253.7nrn紫外线的强度(在距离1米处测定,不加反光罩)为:功率>30W灯,≥90Uw/cm;功率>20w灯,≥60Uw/cm2 ;功率150灯,≥20Uw/cm2。由于这种灯在辐射253.7nrn紫外线的同时,也辐射一部分184.9nm紫外线。故可产生臭氧。
(2)高强度紫外线消毒灯:要求辐射253.7nrn紫外线的强度(在距离1米处测定)为:功率30W灯,>180uW/CM2;11w灯,>30 uW/CM2。
(3)低臭氧紫外线消毒灯:也是热阴极低压汞灯,可为直管型或H型;由于采用了特殊工艺和灯管材料,故臭氧产量很低,要求臭氧产量<1mg/h。
(4)高臭氧紫外线消毒灯:由于采取了特殊工艺,这种灯产生较大比例的波长184.9nrn的紫外线,故臭氧产量较大。
2.3.2.8 紫外线消毒器
(1)紫外线空气消毒器:采用低臭氧紫外线杀菌灯制造,可用于有人条件下的室内空气消毒。
(2)紫外线表面消毒器:采用低臭氧高强度紫外线杀菌灯制造,以使其能在瞬间达到满意的消毒效果。
(3)紫外线消毒箱:采用高臭氧高强度紫外线杀菌灯制造,一方面利用紫外线和臭氧的协同杀菌作用,另一方面利用臭氧对紫外线照射不到的部位进行消毒。
2.3.3 适用范围及条件
2.3.3.1 紫外线可以杀灭各种微生物,包括细菌繁殖体、芽胞
浓度的测定,需测定在230、260和280nm处的消光值,经验数据表明,纯净的核酸溶液A260/A230的消光值比大于或等于2.0;A260/A280大于或等于1.80。A260/A280值过小,说明蛋白未脱净;A260/A230过小,说明有杂质(一般为多酚类或色素)。
这样的提问没有意义
建议自己下去查查资料
一是紫外灯照射出问题了;
也可能是门没关紧,经常接触又断掉,不稳定;
如果成像仪没问题,那很可能就是电脑上操纵拍照的软件在设置上有了问题,应该有配套的说明书的,可以参考;
实在不行,可以报修的,没必要自己找烦恼。
